Well , Peter , you have to do better than that next time , won't you ?   Have I really got to do those exams again , Dad ?   Of course , you have . You must try harder this time .   And must I go back to school ?   No , you needn't do that . You'd better get a part-time job somewhere and go to evening classes .   But Dad , I should be working full-time at my age . I'm nearly 17 .   You ought to have worked harder then you wouldn't have failed your exams . You have to take a job and study .   What else I've got to do ? Join the army ?   Who knows ! That might come to later .
